Dear Community: For GTA02 SD card interference GPS issue, our hardware team provide a hardware fix/workaround for this coexistence bug. Sorry post it late, because we have to make sure this fix works and don't have side effects. Here is the fix: http://www.openmoko.org/wiki/Image:Gta02_gps_10pf_rework_sop.pdf This fix could give almost same performance with SD card out of case. But this work still not suggest do by yourself, also, this fix need proper size capacitor (10 pf with 0402 package), and some solder technique. We saw people ask about service issues of Openmoko devices, and we are working on it. Our sales discussing with our distributor about proper services model, but do not have consensus yet, I will keep update it. Thanks, Tony Tu Openmoko, Inc.

On Fri, 18 Jul 2008 11:28:29 +0200, Neng-Yu Tu (Tony Tu) Kudos to the Openmoko team! This is what's great about an open phone. For any other device, the necessary fix would be a big secret, and making it would be monopoly of the manufacturer and their service partners. With this kind of openness, anybody can either make the fix themself or hire someone on the open market to do it. I'm pretty sure that a cell phone repair shop near you will fix it for you using this instruction. -- Alexey Feldgendler <alexey@feldgendler.ru> [ICQ: 115226275] http://feldgendler.livejournal.com _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
On Fri, Jul 18, 2008 at 12:28 PM, Neng-Yu Tu (Tony Tu) Great work, a hardware solution in two or three days or so! I'd be glad to hear the change of the TTFF with this HW fix & sd compared to no sd. So now we're only waiting for pulster and other distributors to let us know what's the thing to do: Are we allowed to do it ourselves, take it to a phone repair shop or what. Great work, can't wait to get my FR in about 10 days.. r -- | risto h. kurppa | risto at kurppa dot fi | http://risto.kurppa.fi _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I will do this fix next week as soon as my Freerunner arrives, and let you know how it goes. ; -- Jay Vaughan _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Good luck soldering that; however if you happen to be an experienced electronics engineer with access to a work-bench with all the usual tools then my apologies..... I'd just hate to think that comment leads others to think they could effect the repair easily because all we will have is a whole lot of broken freerunners. Regards, Jon _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Its not a warmed-up-butter-knife and the kitchen table style of fix, but I'm sure a few can get through it without poking a hole in their Freerunners. When I do it, I'll be sure to have a big lens around and lay off the coffee (coz of the shakes) for the day .. ; -- Jay Vaughan _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hi,
The last 50 Minutes I drived 8 km around with my bike for catch
coordinates for OpenStreetmap.
I was carefully with Tangogps, so only the one Map came from SD-Card but
the Track was written to the Flash.
The Track looks very good.

Not exactly(that i know of), but on 2007.2 I think you can add your own items to the main application menu, by putting a .desktop file in /usr/share/applications See existing files in that directory for an example .desktop I just tested it by copying and deleting one of the files(ssh'd in from desktop), and it's kinda cool seeing the menu update immediately on the phone screen.

<a class="moz-txt-link-abbreviated" ...I saw something similar yesterday with tangogps. The red track looked like it had been jumping around a lot, but with my indicated location apparently fixed a long way back in the route. I didn't have a tile cached for the area I had walked into. When I zoomed out to a scale where I did have a tile cached it redrew the track, this time following the route I had walked without jumping. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I don't think so so. As far as I can tell, tango GPS just uses the data provided by the GPS chip (via gpsd) and displays your location on the top of the map. It doesn't care if the map is empty, or whatever it contains... Regards, -- MiKael _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
No, that is definitely not the case. But occasionally I have seen this behaviour too on my FR, yet never on the Neo1973s. One interesting observation I made is that my FR has in the beginning often a GPS time offset 15 seconds into the future. It does so even if I feed the time by AGPS. It takes 10-15 minutes until this is corrected by the chip. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Wild guess: Maybe it's reporting raw GPS time, without leap second correction. I haven't observed this myself, but it's suspiciously close to the current GPS-UTC offset of 14 seconds. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Personally, a kit would work for me. I have fine pitch solder and a nice iron, but not enough SMT parts to have that cap on hand (or easily aquired). I suspect others might not be so lucky though. --tim _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

You will need 'flux core solder' (normal 'resin' electronics solder), with a low wattage soldering iron, like 15W. It also helps to apply the solder to all contacts first, before putting the capacitor in place.

The software fix is better than the capacitor because it works on all lines to the card, not just the clock. With just the capacitor on the clock line the other lines may give enough interference to upset the GPS during card access. That's my translation anyway. Another question - might the added capacitor on the clock line cause problems with the lower drive strength that's now default? _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

sorry to be pain in the b%%t, but was testing done to check if there is
any affect on SD card performance? (I am lazy to look now even what pins
at SD are those ;)) just wanted to check

This additional capacitor has been added between clock and GND for the SD card. So it is most probably just there to filter frequencies higher than the clock rate itself. Michael _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
hm... or alter clocking pulse sufficiently for unstable SD performance
with some (or all) SDs... how could we know for sure unless verified
empirically... (noone could guess that having SD impacts GPS for quite
a while, right?)
I am not yet planing to do this hw mod on my phone, thus I can't really
compare, and it would be great if anyone having such modded phone (I
guess OM people) do such a simple test (basic IO testing of SD card
similar to the ones which were posted to this list before).
NB It would be really pathetic if then after new 'fixed' units are
shipped, and new owners start complain that 50% of SD cards do not work
or get significant performance reduction, right? So why not to make sure
(I bet they already did smth like that thus it is just for someone from
OM give results with numbers)

After further testing I can only congratulate the OM-team for their quick and easy fix: whether inside at the window, in a moving train or in narrow streets, the FR is aquiring a Fix consistenly within about 120s from cold start under the most difficult conditions, and of course even faster at consecutive tries ( warm start ). Under normal conditions, a TTFF of 40s seems to be the maximum needed even for a cold start, which in my opinion i= s exceptionally good! The SD-Card (4GB) still works as expected by this RF only fix, and there is no need to unmount it ... Btw, this was all done with the mwester-andy kernel from 080716... Big thumbs up to everyone at OM, now let the mapping begin ;-) Stefan On Fri, Jul 18, 2008 at 1:26 PM, Stefan Fr=F6be <frobiac@googlemail.com> wrote: Great work, and I can confirm this to be working just fine !!!

The previous software-only improvements were of mixed results: only once di= d a fix occur, and by far not as fast as the 34s I got without SD-Card. Will keep you updated on further results this weekend, but so far it is great news to see a fix this quickly!
